Gradually it became clear that it is a fundamental error to try to give the sexual act a psychological interpretation, to attribute to it a psychic meaning as if it were a neurotic symptom. But this is what the psychoanalysts did. On the contrary: any idea occurring in the course of the sexual act only has the effect of hindering one's absorption in the excitation. Furthermore, such psychological interpretations of genitality constitute a denial of genitality as a biological function. By composing it of non-genital excitations, one denies the existence of genitality. The function of the orgasm, however, had revealed the qualitative difference between genitality and pregenitality. Only the genital apparatus can provide orgasm and can discharge sexual energy completely. Pregenitality, on the other hand, can only increase vegetative tensions. One readily sees the deep rift which formed here in psychoanalytic concepts.
